United States Patent 3,124,004 WATCH INCGRPORATING A BARGMETER Willy Zenger, 53 Rue des 22 Cantons, La Chaux-de-Fonds, Switzerland Filed Feb. 8, 1962, Ser. No. 172,002 Claims priority, application Switzerland Feb. 11, 1961 1 Claim. (Cl. 73-386) My invention has for its object a watch incorporating an aneroid barometer provided with a mechanism for transmitting the movement between the barometer box and the cooperating indicating means. According to my invention, said mechanism includes a first lever engaging the barometer box and acting on one of the arms of the second lever rocking in a plane perpendicular to the pivot of the first lever while its other arm extends through a peripheral port provided in a wheel controlling the indicating means, whereby the deformations of the box are transmitted to said wheel and indicating means.

The accompanying drawing illustrates, by way of example, a preferred embodiment of my invention. In said drawings,

FIG. 1 is an elevational partly sectional view of the watch and barometer assembly,

FIG. 2 is a plan view thereof,

FIG. 3 is a plan view of the casing of the transmitting mechanism,

FIGS. 4, and 6 are cross-sections of FIG. 3 through lines IV-IV, VV and VI-VI respectively,

FIG. 7 is a side view of the lever forming part of said mechanism.

The watch illustrated includes a case of which the bottom 1 alone has been illustrated; inside said case is fitted the box of the aneroid barometer including conventionally a corrugated wall 2 welded along its inner edges to two central webs 3 and 4. The lower web 4 is provided with a tenon 5 screwed into the bottom of the watch case; 6 designates a packing and 7 a flat cover-plate. Above the box 2, is inserted a casing 8 enclosing the mechanism providing for the transmission between the barometer case and the cooperating indicating hand 9; above said casing 8 is located the actual watch movement 10.

The mechanism carrying casing 8 includes a body 8a closed by an upper plate 812; the casing body 8a is illustrated in plan view as seen from above in FIG. 3 and FIGS. 4, 5, 6 are cross-sections through lines IVIV, VV and VIVI of FIG. 3. To the bottom of the body 8a and outside the latter is pivotally secured at 12 a lever 13 illustrated separately in FIG. 7, and engaging through its projection 13a the upper surface of the barometer box 2. The free end of said lever 13 acts on one of the arms 14a of the lever 14 pivotally secured at 14b inside the mechanism casing projecting through an opening in the latter and adapted to rock in a vertical plane perpendicular to the longitudinal axis of the lever 13, (FIG. 6). The angular movements of the levers 13 and 14 are allowed by the presence of slots 80 in the walls of the casing 8, said levers extending through said slots. The lever 14 is provided with a second arm 140 which engages a port provided at 15 in the toothed wheel 16. The latter meshes with a pinion 17 rigid with a spindle 18 carrying the indicator hand 9 and 3,124,094 Patented Mar. 10, 1964 subjected to the action of a return coil spring 19. The spindle 18 rotates after the manner of the spindle carrying a center seconds hand inside a sleeve or pipe which is not illustrated and which carries the minute hand of the watch movement 10. The barometer hand *9 moves over a dial, not illustrated, which carries a scale of altitudes corresponding to the pressures to which the barometer is subjected at any point where the watch bearer is standing.

The coil spring 19 has a tendency to urge permanently the wall of the port 15 in the wheel 16 against the arm of the lever 14. When the altitude decreases, the barometer casing 2 has a tendency to contract and the wheel 16 under the action of the coil spring 19 turns, so as to shift the lever 14 and to hold the latter in contact with the lever 13. When the altitude increases, the operation is performed in the opposite manner against the spring 19.

What I claim is:

The combination of a watch and aneroid barometer, comprising a case having a bottom, an aneroid barometer capsule disposed in said case and mounted on the bottom thereof, an inner casing overlying said capsule and provided with slots, a watch movement overlying said inner casing and having a dial above said movement, said inner casing being sandwiched between said capsule and movement, a first lever pivotally mounted in said casing for pivotal movement about an axis parallel to the bottom of said case and extending through a slot in said casing to engage the upper surface of said capsule so as to be movable by said capsule, a second lever pivotally mounted in said casing for pivotal movement about an axis parallel to the bottom of said case and perpendicular to the pivotal axis of said first lever, said second lever engaging said first lever so as to be moved thereby, a gear wheel rotatably mounted in said casing for rotation about an axis perpendicular to the bottom of said case and connected with said second lever to be oscillated by the pivotal movement of said second lever, a spindle rotatably mounted in said casing and extending up through said watch movement, and dial indicating means fixed on said spindle and extending over said dial, a pinion on said spindle in said casing, driving connections between said pinion and said gear wheel, whereby movement of said first lever by said aneroid capsule is transmitted through said second lever, gear wheel and pinion to said spindle, and means in said casing biasing said spindle in a direction corresponding to movement of said first lever toward said aneroid capsule.
